| |
The DNA-AI-207 - analog input data acquisition board features 16 differential input channels with maximum sampling rate of 1kS/s per channel, wide range of gains, 18-bit resolution, and ±10V input range. Additionally, the DNA-AI-207 provides a dedicated CJC channel. The DNA-AI-207 is designed for mid- to low-speed high-resolution signal measurement. It represents an ideal solution for precise temperature measurement over a long period of time.
Another key feature of the DNx-AI-207 is the oversampling engine, allowing the board to automatically acquire as many samples as possible for the given gain/speed and average them, thus dramatically improving the noise floor. |
